"The letters of S. P. Botkin from Bulgaria. 1887": The return of the manuscript in Russia

The previous report partially brought to light history of publishing of "The letters of S. P. Botkin from Bulgaria 1877". The original letters were abroad for many years and they were returned to the USSR in 1974 by grandchildren of S. P. Botkin, S. P. Chekhov and D. P. Chekhov, who resided in France. The circumstances of handing over of the letters to the N. A. Semashko Institute of Health Organization and Social Hygiene are presented. The letters have not been republished for 130 years, but their historical, moral and educational significance remains actual and nowadays. The modern edition of the complete manuscript, along with introductory article and detailed scientific commentary, will become a significant contribution to representation of biography of S.P Botkin, to supplementation of written sources about the Russian-Turkish war of 1877-1878, and to comprehension of centuries-old Middle Eastern geopolitics of Russia.
